The research shows that asymmetry information can cause sluggish behaviour for the same type of employees, the exogenous layoff probability can restrain labour positivity and threaten the efficient labour of the employees, and reduce the agent cost. While endogenetic layoff probability cannot impact on the function of the assembled mechanisms consisting of promotion and fixed income under asymmetry information, which can avoid the moral risk of employees to achieve the same degree of their labour under symmetry information.

研究表明：非对称信息会诱导同类员工偷懒行为，外生裁员概率抑制员工的劳动积极性，对员工的有效劳动构成一种威胁，但裁员概率降低了代理成本；外生裁员机制并不影响信息非对称下的晋升激励和固定收入组合机制持有的避免员工道德风险的功能，实现员工对称信息下的努力程度；以绩效评估为特征的内生裁员机制能够促使异类员工更加努力工作，提高产量，相应地也增加了工资支出；高能员工比低能员工更努力，提高员工裁员绩效标准和高能员工比例，有利于降低代理成本。

Based on the prior information obtained by qualitative inversion, the two stages inversion method was put forward. That is, the first stage is that distinguishing the high-quality element and non- high-quality element, and determining the initial iteration value of element sound velocity reasonably. The second stage is that treating differentially the constraint weights of the high-quality element and non- high-quality element, and then quantitatively inversing the final sound velocity distribution. The results of two concrete specimens indicate that the two stages inversion method can inhibit artifacts effectively and has better defect identification effect than normal one stage inversion.

在获取定性反演先验信息的基础上，提出了两阶段反演的方法：第一阶段，区分优质像元和非优质像元，合理确定像元声速的迭代初值；第二阶段，区别对待优质像元和非优质像元的约束权重，定量反演最终的速度分布。2个混凝土试件的模型试验表明，两阶段反演能有效抑制伪像，具有比常规的一阶段反演更好的缺陷识别效果。

The use of acid protease in the production of machine-made yellow rice wine (by non-glutinous rice) could provide nitrogen source for the growth and reproduction of microzyme and accelerate rapid reproduction of microzyme (which improve fermentation stability and capability), decompose proteins (which advanced the use of amylum in raw materials and increased wine yield), and settled the commonly existed problems of low aminophenol nitrogen content and non-sugar solids content.

Low- protons can be efficiently heated by the enhanced Alfvén waves. And this efficient heating process is attributed to nonresonant wave-particle scattering that leads to randomize protons motion.

本文的研究重点是日冕加热过程的准线性动理学，即低的质子能被阿尔芬波有效加热的问题，这一有效加热主要是由于波粒非共振散射使粒子运动无规化而实现的。

Ultrasound and scintigraphy are non-invasive methods used to detect urinary extravasation. Reconstructed CT ureteropyelography has also been employed for the detection of urinary extravasation after renal transplantation. MRI imaging can show the renal function of the transplanted kidney and the extravasation. MRI is an effective non-invasive alternative for the diagnosis of urinary extravasation after renal transplantation especially when ultrasound and scintigraphy are inconclusive.

超音波及核子医学检查是诊断肾脏移植后尿液外漏的非侵袭性的方法，MRI 可以明确的侦测尿液外漏，而且可以知道移植的肾脏是否有功能，这能决定是否需要及是否值得再一次手术，所以MRI 是另一个可以有效且非侵袭性检查，在超音波及核子医学检查没有明确诊断时，可以帮助诊断。

At the same time, chaotic pseudo-random sequences generator based on nonlinear dynamic filter security model are constructed to select the frequency hopping points for NDFT, improving the overall system security. 3、Aiming at replay attack of networks in the remote speaker recognition systems and distributed databases speaker recognition systems, a time-stamp watermarking method is brought, which quantizes magnitude coefficients of NDFT. The time-stamp watermarking is embedded into the user's voice sample/voice characteristic information to resist on the replay attack.

同时该类算法采用以非线性动力学滤波器为基础的伪随机序列发生器构造跳频序列来选择频率变换点集合，有效提高了系统的安全性。3、针对远程说话人识别系统以及数据库分布式说话人识别系统存在易受网络重放攻击的缺陷，本文给出一种基于非均匀傅立叶变换的&时间戳&水印量化算法，通过把时间戳水印嵌入待识别用户的语音样本/语音特征信息中，可以有效解决此类缺陷。
